FAQ
How long does it take to perform an SEO audit?
A basic SEO audit covering technical issues, on-page checks, and backlink review typically takes between four and eight hours for a site with up to 500 pages. Larger sites or more detailed audits that include competitor analysis and content gap work can take several days. Using an automated crawl tool reduces the data-gathering time significantly, but analysis and prioritisation still require human judgement.
What tools do I need to perform an SEO audit?
The minimum toolkit for an SEO audit is Google Search Console, which provides indexation and Core Web Vitals data, and a crawl tool such as Screaming Frog or a cloud-based alternative. PageSpeed Insights is free and covers site speed at a URL level. A backlink tool rounds out the set for a complete audit.
How often should I run an SEO audit on my website?
Running a full SEO audit every quarter is the standard recommendation for most sites. High-traffic or frequently updated sites, such as ecommerce catalogues, benefit from monthly crawls to catch new issues quickly. Search Console should be checked weekly regardless of your full audit schedule.
What is the difference between a technical SEO audit and an on-page SEO audit?
A technical SEO audit focuses on how well search engines can crawl and index your site, covering issues such as server errors, redirect chains, canonical tags, and site speed. An on-page SEO audit focuses on the content and structure of individual pages, including title tags, heading hierarchy, keyword usage, and internal links. A complete SEO audit covers both.
Key Answer
How to perform an SEO audit:
- Crawl your site to find broken links, redirect chains, and indexation errors.
- Audit title tags, meta descriptions, heading structure, and internal links on every key page.
- Review your backlink profile for low-quality or spammy referring domains.
- Check Core Web Vitals using Google Search Console and PageSpeed Insights.
- Score every issue by severity and ease of fix.
- Prioritise high-severity quick wins first, then schedule remaining fixes into your development cycle.
- Re-crawl after fixes to confirm issues are resolved.
- Repeat the full audit quarterly to catch new problems early.
